Use of chitobiose in preparation of bacteriostatic fishery drugs or bacteriostatic fish feeds

Abstract

The invention discloses use of chitobiose in preparation of bacteriostatic fishery drugs or bacteriostatic fish feeds, the inhibited bacteria are vibrio anguillarum, aeromonas hydrophila, aeromonas sobria, aeromonas punctata and flexibacrer marilimys. The chitobiose has obvious antibacterial activity, is a natural antibacterial substance free of toxic and side effects, and can significantly improve the disease resistance ability of cultured fishes by using as a fishery drug to add into basal feeds.

Description

technical field [0001] The invention relates to the antibacterial application of a substance, in particular to the application of chitobiose in the preparation of antibacterial fish medicine or antibacterial fish feed. Background technique [0002] In the production of farmed fish, people often use antibiotics to prevent bacterial infection and promote animal growth. However, antibiotics also kill beneficial bacteria while killing harmful bacteria, and long-term use not only makes bacteria resistant to antibiotics, but also drug residues and the impact on the quality of animal products are a serious problem. [0003] It has become an inevitable trend in today's aquaculture production to develop and utilize new feed additives that are pollution-free, residue-free, and drug-resistant, and can improve the resistance of animals and prevent animal diseases. As a new type of green feed additive, chitobiose is rich in resources, non-toxic, and has no side effects. It has fewer pro...

Problems solved by technology

[0004] Fishing medicines in the prior art and their existing problems are as follows: pyrethroids: the safe concentration range is small, and the allowable safe concentration is low, and a slight deviation will cause a devastating blow to farming; organic phosphorus: organic phosphorus seriously damages the waters It is a pesticide that is about to be banned; copper sulfate: low drug efficacy, large dosage, excessive copper residue will cause liver poisoning, and high price; chlorine preparation: chemically unstable, inconvenient for packaging and transportation, there are Strong pungent smell with large dosage and high price; Abamectins: Although they are a broad-spectrum insecticide, the effect is not obvious, and the dosage is too large and the cost is too high
